              byte[] key)

Method Detail

parse

public static DNSKEY parse(DataInputStream dis,
                           int length)
                    throws IOException

Throws:

IOException

getType

public Record.TYPE getType()

Description copied from class: Data

The payload type.

Specified by:

getType in class Data

Returns:

The payload type.

getKeyTag

public int getKeyTag()

Retrieve the key tag identifying this DNSKEY. The key tag is used within the DS and RRSIG record to distinguish multiple keys for the same name. This implementation is based on the reference implementation shown in RFC 4034 Appendix B.

Returns:

this DNSKEY's key tag

serialize

public void serialize(DataOutputStream dos)
               throws IOException

Description copied from class: Data

The internal method used to serialize Data subclasses.

Specified by:

serialize in class Data

Parameters:

dos - the output stream to serialize to.

Throws:

IOException - if an I/O error occurs.

toString

public String toString()

Overrides:

toString in class Object

getKeyLength

public int getKeyLength()

getKey

public byte[] getKey()

getKeyBase64

public String getKeyBase64()

keyEquals

public boolean keyEquals(byte[] otherKey)

isSecureEntryPoint
